摘要
针对百叶窗形蜂窝构件窗相比于矩形蜂窝构件窗的太阳辐射透过率高但热损系数增加的特点,为比较两者对普通双层窗热性能的改善程度,采用了3个不同纬度地区的气象数据,对这三种窗体结构进行了全年模拟计算。结果表明相比于普通双层窗,百叶窗形蜂窝构件窗和矩形蜂窝构件窗的热性能都得到了很大的提高,其中百叶窗形蜂窝构件窗又优于矩形蜂窝构件窗。但随着纬度的升高、太阳辐射的降低、环境温度的下降和当地风速的增加,两者之间的差别变得越来越小。
Comparing with the square honeycomb window, the solar transmittance of the shutter-type honeycomb window was improved and had the higher heat loss coefficient simultaneously. Based on the meteorological data in 3 different latitude areas, annual simulation was done for the thermal performance improvement of the shutter-type honeycomb window and the square honeycomb window comparing with the normal double-glazing. The results showed that the thermal performances of the shutter-type honeycomb window and the square honeycomb window were highly enhanced. The thermal performance of the shutter-type honeycomb window was better, although the superiority diminished with the solar radiation reduced, ambient temperature lower and local wind velocity increased in the higher latitude area.
